Hunleys discovery was described by William Dudley, Director of Naval History at the
Naval Historical Center as "probably the most important find of the century." The discovery of
Hunley has been claimed by two different individuals. Underwater archaeologist
E. Lee Spence, president,
Sea Research Society, reportedly discovered
Hunley in 1970, and has a collection of evidence claiming to validate this, including a 1980 Civil Admiralty Case. The court took the position that the wreck was outside the jurisdiction of the
U.S. Marshals Office, and no determination of ownership was made. On 13 September 1976, the National Park Service submitted the Sea Research Society's (Spence's) location for
H. L. Hunley for inclusion on the
National Register of Historic Places. Spence's location for
Hunley became a matter of public record when
H. L. Hunleys placement on that list was officially approved on 29 December 1978. Spence's book
Treasures of the Confederate Coast, which had a chapter on his discovery of
Hunley and included a map complete with an "X" showing the wreck's location, was published in January 1995. Diver Ralph Wilbanks located the wreck in April 1995 while leading a
NUMA dive team originally organized by archaeologist Mark Newell and funded by novelist
Clive Cussler, who announced the find as a new discovery and first claimed that the location was in about of water over inshore of
Housatonic, but later admitted to a reporter that that was false. The wreck was actually away from and on the
seaward side of
Housatonic in of water. The submarine was buried under several feet of silt, which had concealed and protected the vessel for over a hundred years. The divers exposed the forward hatch and the ventilator box (the air box for the attachment of her twin snorkels) to identify her. The submarine was resting on her starboard side, at about a 45-degree angle, and was covered in a thick encrustation of
rust bonded with sand and seashell particles. Archaeologists exposed part of the ship's port side and uncovered the bow dive plane. More probing revealed an approximate length of , with the entire vessel preserved under the sediment. On 14 September 1995, at the official request of Senator Glenn F. McConnell, chairman, South Carolina
Hunley Commission, E. Lee Spence, with South Carolina Attorney General Charles M. Condon signing, donated
Hunley to the State of South Carolina. Shortly thereafter, NUMA disclosed to government officials Wilbank's location for the wreck which, when finally made public in October 2000, matched Spence's 1970s plot of the wreck's location well within standard mapping tolerances. Spence avows that he discovered
Hunley in 1970, revisiting and mapping the site in 1971 and again in 1979, and that after he published the location in his 1995 book he expected NUMA to independently verify the wreck as
Hunley, not to claim that NUMA had discovered her. NUMA was actually part of a
SCIAA expedition directed by Dr.
Mark M. Newell and not Cussler. Dr. Newell swore under oath that he used Spence's maps to direct the joint SCIAA/NUMA expedition and credited Spence with the original discovery. Dr. Newell credits his expedition only with the official verification of
Hunley. The
in situ underwater archaeological investigation and excavation culminated with the raising of
Hunley on 8 August 2000. A large team of professionals from the Naval Historical Center's
Underwater Archaeology Branch,
National Park Service, the
South Carolina Institute of Archaeology and Anthropology, and various other individuals investigated the vessel, measuring and documenting her before removal. Once the on-site investigation was complete, harnesses were slipped underneath the sub and attached to a truss designed by
Oceaneering International. After the last harness had been secured, the crane from the recovery barge
Karlissa B hoisted the submarine from the sea floor. She was raised from the open waters of the Atlantic Ocean, just over from Sullivan's Island outside the entrance to Charleston Harbor. Despite having used a sextant and hand-held compass thirty years earlier to plot the wreck's location, Dr. Spence's accuracy turned out to be well within the length of the recovery barge, which was long. On 8 August 2000, at 08:37, the sub broke the surface for the first time in more than 136 years, greeted by a cheering crowd on shore and in surrounding watercraft, including author Clive Cussler. Once safely on her transporting barge,
Hunley was shipped back to Charleston. The removal operation concluded when the submarine was secured inside the
Warren Lasch Conservation Center, at the former
Charleston Navy Yard in North Charleston, in a specially designed tank of fresh water to await conservation until she could eventually be exposed to air. The exploits of
Hunley and her final recovery were the subject of an episode of the television series
The Sea Hunters, called
Hunley: First Kill. This program was based on a section ("Part 6") in Clive Cussler's 1996 non-fiction book of the same name (which was accepted by the Board of Governors of the Maritime College of the State University of New York in lieu of his Ph.D. thesis). In 2001, Clive Cussler filed a lawsuit against E. Lee Spence for unfair competition, injurious falsehood, civil conspiracy, and defamation. Spence filed a countersuit against Cussler, in 2002, seeking damages, claiming that Cussler was engaging in unfair competition, tortious interference, and civil conspiracy by claiming Cussler had discovered the location of the wreck of
Hunley in 1995 when she had already been discovered by Spence in 1970, and that such claims by Cussler were damaging to Spence's career, and had caused him damages over $100,000. Spence's lawsuit was dismissed through summary judgment in 2007, on the legal theory that, under the Lanham Act, regardless of whether Cussler's claims were factual or not, Cussler had been making them for over three years before Spence brought his suit against Cussler; thus the suit was not filed within the statute of limitations. Cussler dropped his suit a year later, after the judge agreed that Spence could introduce evidence in support of his discovery claims as a truth defense against Cussler's claims against him.
